Abstract
The invention relates to a label with antiforgery security, comprising an adhesive layer applied to a lower face of a support layer. In or on the bare face of the adhesive layer, a plurality of inclusions are present which contain at least one reversibly detective additive. When the label is bonded to a base, the inclusions are forced into the adhesive layer such that layers of the label above the inclusions are deformed, thereby forming haptically distinguishable and optically visible bumps in a surface of an upper support layer.
Claims16
A label with improved antiforgery security, the label comprising:
- at least one carrier layer with an adhesive layer on its lower side,
- a plurality of inclusions in or on an exposed side of the adhesive layer, wherein the plurality of inclusions comprise at least one reversibly detectable additive,
- wherein the label bonds to a substrate by pressing at least one of the plurality of inclusions into the adhesive layer such that the at least one carrier layer of the label located above the plurality of inclusions undergoes deformation and produces one or more haptically perceptible and optically visible impressions in a surface of an upper carrier layer of the label.
